Online Fire Academy

Hey guys im new to the site and just wanted to throw out a question hoping to get some feedback.. Why are so many people opposed to online fire academies? Back in the spring i completed an online fire academy and as of yesterday i got certified as a emt-b. I passed the same state written fire test as the resident guys and got my seals too. I took the same state skills test as the resident guys and passed. Some people cant quit their full time job for 3-4 months. Guys im not up here throwing a fit or trying to start a feud, im just wanting some opinions...
